M.A.P sensor DAIHATSU SIRION (M3_)

I have a Daihatsu Sirion 11 M300 1.3 petrol automatic,
registered in 2008, the ABS warning light and the handbrake warning light on
the dashboard will not go out. So far I have had the car to the mechanic who
looks after it and a local, well established auto electrician, near to where I
live, they could not diagnose the fault because they did not have the correct
diagnostic tool, I then took it to a Daihatsu dealer who told me that, after
reading the error codes, it needed a new ABS pump, which I duly bought (880 GP
pounds) they fitted the pump and they told me that 2 error codes had
disappeared but the error codes for the rear wheels were still there, codes
CO215 CO210 are still showing. I have bought from Autodoc two rear axle
bearings with sensor as per the website relevant search, these have now been
fitted and the fault is still there, my mechanic and the auto electrician are
at a loss, as am I, there is continuity from all the wirings from wheels to ABS
ECU, we have a reading from both front wheel of 1.10 and a lesser reading of 0.895
from both rear wheel, when rotated, there has been a ”blink” test performed and
the car was run at the required speed and the lights are still on. Can anybody
help me resolve this problem, incidentally the interior courtesy lights have
stopped working as well at the same time, and all fuses have been checked.

Below is part of the report from the Daihastu dealer and
their suggestions,

 

New ABS pump fitted. After setting new ABS pump to normal
operating mode and clearing codes again,

C0215 and C0210 error codes come back on. Possibility of
readings not high enough for normal operation.

Suspect needs new ABS wires fitted to eliminate possible
wire fault, NOT FITTED, if no better

need rear hub and bearings fitting.   NOW FITTED

 

Blimey, mate! You've got yourself in a right pickle with that MAP sensor, haven't you? I once accidentally shorted my Vauxhall's oxygen sensor to the battery, and let me tell you, it was about as useful as a chocolate teapot after that. Your diagnosis sounds spot on, though. A knackered MAP sensor can definitely keep your motor from firing up. Good call on getting a new one. Just keep your fingers crossed that the short didn't fry anything else in the process. Maybe next time, stick to changing the radio station instead of playing electrician, eh? 😉

Hello there! I couldn't help but notice your Daihatsu Sirion troubles. While I can't speak to the MAP sensor issue, I've had my fair share of headaches with ABS problems on my old Daihatsu. Those C0215 and C0210 codes are proper gremlins, aren't they? Have you considered that your ABS issues might be related to a faulty wheel speed sensor? Sometimes they can cause all sorts of havoc, including those pesky warning lights. It might be worth having a look at the wiring near the wheel hubs – road debris can sometimes damage them. Don't lose hope, though. These little Daihatsus are tough as old boots once you sort out their quirks!

Oi, you lot! I've been following this thread, and I've got to say, electrical gremlins are the worst, aren't they? Makes you wish for the good old days of carburetors and distributor caps. But I digress. To the chap with the Sirion ABS woes – have you checked the ground connections? Sometimes a dodgy earth can cause all sorts of weird behavior, including your interior lights going on the fritz. As for the MAP sensor short, that's a new one on me. Reminds me of the time I accidentally connected my multimeter to the wrong terminals and nearly turned it into a firework display. Anyway, best of luck sorting it all out. Maybe treat yourself to a pint afterward – sounds like you've earned it!
